Sexual Reproduction in Flowering Plants

How many meiotic and mitotic divisions need to occur for the development of a mature female gametophyte from the megaspore mother cell in an angiosperm plant?

  1. A.2 meiosis and 3 mitosis
  2. B.1 meiosis and 2 mitosis
  3. C.1 meiosis and 3 mitosis✓
  4. D.No meiosis and 2 mitosis

Solution

One meiosis of the megaspore mother cell gives four megaspores; the surviving one undergoes three mitotic divisions to form the 8-nucleate embryo sac. So 1 meiosis and 3 mitoses.
